My product is displaying an invalid barcode. How can I rectify this issue?

Article last modified on: Mon, 18 Sep 2023

Barcodes play a crucial role in selling products on Walmart. To address this problem, please follow these steps:

  • Ensure you have a valid 12-digit UPC code for your products.
  • If you do not possess a valid UPC code, you can acquire one from Speedy Barcode.
  • Update the UPC codes within your Shopify store. This update will automatically synchronize with our app.
  • Alternatively, you have the option to directly update the UPC codes in our app using a CSV file or the product editing feature.

Once the update is complete, proceed to upload your product.
